About Tanaka Airsoft Revolver
The Airweight Model 37 revolver was introduced in 1951 and is basically the iconic Model 36 but made with an aluminum frame to make it lighter, Japan in 2003 and 2005 purchased the M37 with a lanyard hoop for their National Police Agency and is issued to the Japanese Police alongside the Smith & Wesson M360J Sakura. 
The Tanaka S&W M37 Air Weight 2-inch J-Police Steel Jupiter Finish gas revolver is a faithful replica of the Japanese police gun as a gas revolver. This gun is a true gem, at first glance, looks as if it is a metal gun due to the premium JUPITER finish, JUPITER stands for Jewelish Ultra Plated InTEgrate Resin. As such, this detailed finish can easily deceive even the keen-eyed among us, as the revolver is made of high-quality resin and plastic. Do not be fooled, though plastic, nothing about his M37 can be considered "cheap" as it carries a fair amount of weight and when paired with an assortment of metal parts, it certainly feels as if it's a metal gun. Metal parts such as the hammer, trigger, and cylinder give the pistol a real-life-like aesthetic making it not only a great choice for collectors but can even be used in film or cosplay as a prop!
Shooting the gun is a joy as the double action is smooth and direct, pulling the trigger slowly feels buttery with no "grit" feeling at all. When the hammer is pulled back, the trigger breaks soft and the sound of the cylinder rotating exemplifies the effort Tanaka put in to make this revolver a standout.
The M36 is cylinder-loaded with a loader, the shells are not removable. This allows for a higher capacity, 10 rounds, and you don't have to worry about losing shells. The hop-up is fixed and is perfectly designed to work with HFC134a or duster gas.
